FOLDING OR COLLAPSIBLE CHAIR.

SPECIFICATION forming part of Letters Patent No. 561,136, dated June 2,1896. Application filed February 27, 1896- Serial No. 580,965. (Nomodel.)

To aZZ whom it may concern.-

Be it known that we, CHARLES J. SCHULTE and CHARLES F. WEHMEYER,citizens of the UnitedStates,'residing at St. Louis, in the State ofMissouri, have invented certain new and useful Improvements in Foldingor 001- lapsible Chairs, of which the following is a full, clear, andexact description, reference being had to the accompanying drawings,forming a part hereof.

Our invention has relation to improvements in folding chairs; and itconsists in the novel arrangement and combination of parts, more fullyset forth in the specification, and pointed out in the claims.

In the drawings, Figure 1 is a side elevation of the chair folded. Fig.2 is a side elevation of the chair unfolded into the form of a vehicle.Fig. 3 is a sectional detail on the line so a; of Fig. 2, and Fig. 4 isa section on line y y of Fig. 2.

The object of our invention is to construct a childs chair which underordinary circum-.

stances will serve the purposes of a high chair, and which under othercircumstances can be folded or converted into a wheeled chair or vehicleby the simple manipulation of certain parts, the details of which willbe more fully hereinafter described.

A further object is to construct such a chair with a minimum number ofparts and to simand the latter being mounted near the lower end of saidleg. When the device is used as a high chair, the upper ends of theextensionlegs 5 abut against the front transverse strip 8, secured tothe under surface of the seat adjacent to and parallel to the front edgethereof. The upper ends of the extension-legs are connected by the links9, secured, respectively, along the outer and inner surfaces of therespective legs 4 and 5, and the lower ends of the said extension-legsare similarly connected by the links 10 at a point above the wheels 7,the object of connecting the links on opposite faces of the legs beingto allow the latter to freely fold, about the links when the chair isunfolded, as best seen in Fig. 2. Pivotally connecting the side bars 11of the back with the lower extremities of the extensions 4 are thebrace-bars 12 and the curved handle-bars 13, the medial portions of thelatter and the lower extremities of the legs 4 embracing the free endsof the reduced extensions 14 of the rounds 15, which respectivelyconnect the handle-bar and leg on one side of the chair with itscorresponding handle-bar and leg on the opposite side, the extensions 14each passingthrough the braces 12 to effect such connection.

When the device is normally used as a high chair, the parts are foldedas seen in Fig. 1, in which case the shoulders 16, formed in thehandle-bars adjacent to the pivotal ends of the braces 12, are firmlylooked under and against the lower surface of the seat 1, and the freeends of the handle-bars are additionally secured to one of the legs 4 bya swinging latch 17. When thus locked, the chair cannot be accidentallycollapsed by the child using it. The free ends of the handle-bars areconnected by a rod 18, whose end is shown by the dotted lines in Figs. 1and 2. \Vhen the parts are unfolded, as in Fig. 2, the members 13 serveas the handle-bars for the carriage or vehicle thus resulting.

Having described our invention, what we claim is 1. In a folding chair,a suitable seat, rigid legs depending from the same, extensions pivotedto said legs, wheels carried by the front pair of said extensions, anabutting strip carried by the seat against which the extensions may restwhen the chair is in its normallyraised position, suitable linksconnecting the front and rear extensions, the opposite ends of each linkbeing pivotally secured along opposite sides or surfaces of the frontand rear extensions respectively, a back for said chair, foldingconnections between said back and one pair of the extensions, and meansforming part of said connections for locking the parts against the seatwhen the chair is in its normally-raised position, substantially as setforth.

2. I11 a folding chair, a suit-able seat, rigid legs depending from thesame, extensions pivoted to said legs, wheels carried by the front pairof said extensions, an abutting strip carried by the seat parallel tothe front edge thereof against which the free ends of the extensions mayrest or be held when the chair is in its normally-raised position,suitable links connecting the front and rear extensionlegs, one end ofeach link being secured pivotally along the outer surface of the rearextensions and along the inner surface of the front pair of extensions,a suitable back for said chair, suitable handle-bars pivoted to theback, rounds having reduced extensions connecting the handle-barsv atapproximately their medial portions, suitable braces pivotally connectedto the reduced extensions of the rounds, suitable rounds connecting thebases of the rear pair of extension-legs, said latter rounds havingreduced extensions conneeted pivotally to the opposite ends of thebraces, shoulders formed with the handlebars in such position that whenthe device is folded to raise the chair the said shoulders will be inengagement with the under surface of the seat, and a suitable latchadapted to further secure the free ends of the handlebars to the rearextension-legs, the parts all operating as and for the purpose setforth.

3. In a folding chair, a suitable seat, a back for the same, suitabledepending legs, extensions for said legs, suitable handle-bars pivotedto the back, suitable braces pivotally connecting the handle-bars andrear extensions, and shoulders formed with the handlebars in suchposition that when the device is folded to raise the chair, saidshoulders will be in engagement with the under surface of the seat,substantially as set forth.

In testimony whereof We afiix our signatures in presence of twowitnesses.
